Chinese petroleum network news through continuous tracking and evaluation for a period of one month, three located in Malang sag Santanghu basin of Xixia No. 1 ditch tectonic belt Ma 216H wells in the Xishanyao Formation by volume after fracturing Nissan 14 cubic meters of crude oil, as of August 15th has been stable for more than 30 days, the cumulative oil production of 350 cubic meters, and the ratio of oil to rise.
Ma 216H well is a shallow horizontal well with a drilling rate of 95.2%. According to the reservoir characteristics and difficulties, the Tuha technical team has improved the fracture diversion capacity through horizontal wells + volumetric fracturing, effectively supported the cracks and improved the volume of reservoir reconstruction. At the same time, the fracturing fluid system and thickener concentration are optimized to further increase the production of single well.
Turpan Hami basin three Tang horse 216H wells through the integration of geological engineering production technology to obtain high yield, further to the undeveloped reserves to achieve the re evaluation, proved reserves producing level of low pressure sandstone using horizontal well fracturing technology can greatly improve the yield and wells three Santanghu basin formed, horizontal well pressure sandstone reservoir in the use of technical efficiency the route, is expected to achieve three Santanghu Xishanyao Formation sandstone reservoir. The overall oil pressure.
